"Incorrect Doctrine"
I would be very careful about highlighting this aspect for the simple reason that the bible is open to multiple interpretations and notions of what is correct or incorrect can be somewhat subjective.
However, it can work well if the intention is to highlight how Watchtower's teachings have changed over the decades and continue to change, thus demonstrating that their policy of shunning those who openly disagree with a particular teaching not clearly and explicitly stated in the bible, and which is subject to change in the future, is grossly unreasonable and amounts to coercing members to conform to teachings purely for the sake of conforming.
